92 454 wont idle

Hello,
I have a 92 1-ton 454 dually. The truck will not stay runnning on it's own when you first start it up. It doesn't matter if it's up to temp. or not. Once you take it down the road and stop at a light, it sits there and idles fine, but when you start it up, it wont idle. No codes come up. I just put plugs, wires, cap rotor etc. and it didn't seem to make a difference. Also checked for vacuum leaks, but couldn't find any.

The truck runs great once you actually drive it, but it just wont idle when you start it up, hot or cold. Any suggestions?
